EDWARD OSCAR KUENDIG, F CANTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TOARTHUR S. KOENREICH, OF CANTON, OHIO AlR-TJOVING APPARATUS Applicationfiled December 18, 1928.

The invention relates to improvements in air moving apparatus and moreparticularly7 to supports for an air displacement unit of a vacuumcleaner such as shown in the application of Walter S. Simpson, forvacuum cleaners, filed September 17, 1928, Serial No. 306,524, by meansof which the unit may he utilized as a blower, for drying,` hair andother air impelling uses.

Almost every home is provided with one kind or another ot vacuum cleanerwhich is used for-a short time every day for cleaning` purposes.However, the air displacement unit of such cleaner is not adapted foruse other than for cleaning purposes, except that they may sometimes beused as blowers in a manner illustrated by Patent No. 1,293,250 issuedto Walter G. Trautman.

When such a construction is used as a blower, the blower nozzle has nopermanent support and the blower nozzle may not he directed in anydirection except through the medium of a person handling, holding, anddirecting the same. Such use is restricted and encumhered by thepresence of the vacuum cleaner handle, nozzle and other partsunnecessary when the cleaner is being utilized as a blower.

For instance if it were desired to use suc-h a cleaner as a hairdryer inthe home, it would he necessary to have some person other than the onewhose hair is being dried, manipulate and direct the nozzle in properdirections in order that the blast may be used to eifectually dry thehair.

The objects of the present invention include the provision of a simpleinexpensive support AFor the air displacement unit ot a vacuum cleaner,which may be included as an attachment for the vacuum cleaner` when thesame is sold, and hy means of which the vacuum cleaner may he easily andreadily converted ior use as a hair dryer. adapted for beingconveniently located with reference to the person whose hair is beingdried, and for heing manipulated and directed in any direction by thatperson without the aid of another.

These objects are attained by the present improvement, preferredarrangements of Serial No. 326,845.

which are hereinafter set forth in detail, and may inclu-de a supportmember for the air displacement unit of a vacuum cleaner, the supporthaving a tubular post for connection with the inlet orifice extension ofthe air displacement unit, by means of which the unit i may be swivelledin or on the tubular post, and the tubular post being provided at one ofits end portions with an opening or openings tor the admission of air tothe air inlet orilice of the air displacement unit.

Valve means may also he provided for the opening or openings in thetubular post tor crritrollingl the quantity of air admitted to the airdisplacement unit inlet oriice.

Several embodiments of the invention are illustrated in the accompanyingdrawings, in which Figure l is an elevation of a vacuum cleaner. the airdisplacement unit of which may he easily and readily converted for useas a hair dryer or other air impelling apparatus;

Similar numerals of reference refer to corresponding,` parts throughoutthe various ligures of the drawings.

The air displacement unit generally indicated at 15, is provided with anangled nozzlc tube 1G, rigidly secured to the inlet orifice extension 17b the clam infr screw 18 andl a nozzle 19=is swivelled at the lowerendof the, nozzle tube 16.

The outlet orifice connection 20, of the air displacement unit 15, maybeA provided with a dust collector bag` 21, r nd the unit may also beprovided with a handle 22 for manipulating the cleaner. Convenientlylocated adjacent the handle 22, is the switch 28, for the motor 24, ofthe air displacement unit, and the wires 25 may lead to' any suitablesource ot electric power supply.

The centrifugal impcller 'tan 2o may he mounted` in the fan casingr 27and driven by the motor 24 as shown in Fig. 2 of; the drawings;`

lVhen it is desired to utilize the air displacement unit 15 of thevacuum cleaner' as a blower unit and more' particularly as a hair dryer,the nozzle tube 1:6" may be disconnected from the inlet oriiiceiextension 17 by loosen ing the clamping' screw 18, and thedust collectorbag4 21 may be disconnected from the outlet orifice connection 20.

The inlet.oriiceexten'sion 17 may then have nipple connect-ion 28rigidly1 secured thereto', by the' clamping screw 18, and aportion ofthe nipple connection 28, may then be swivelled ini the tubular post 29,which may extend vertically of the support indicated at 80.

For admitting' air to the air inlet orifice of the air displacement unit15. the' support 8() may be-proif'ided: with legs 31 for spacing the same from a table or other 'H at surface K upon which the support rests;and on openingr 32 may be providedifn the support aligned with the duct33 of the post 29.

'llhe tubular post 29 ina-y be connected to the support by thescrews-oi"rivets 34, and for .simplifying the construction of the support. thetubular post 29 may be a casting similar to the inlet oriiice extension17 of the air displacement unit 15: but the clamping screw 35 thereof.will not be used to clamp the nipple 28 il the clampingT screw 18 isused tor that purpose. for it is usually dcsired to provide a swivelconnection between the support 30 and the air displacement unit l 5.

A nipple connection 86 may be connected with the outlet orifice 2O ofthe unit 15, and a nozzle 37 may be applied to one end thereof as shownin Fig. 2 of the drawinos. The nozzle 37 may be made of rubber and maybe the attachment supplied with the vacuum cleaner for use when'cleaning upholstery.

The construction and arrangement shown in Fig. 2 maybe read-ily andsatisfactorily used as a hair dryer in which the displaced airflowsbetween the support 30 and the table A, then upward through theopening 32, the tubular post 29, the nipple 28, and the inlet orificeextension 17, to the iinpeller fan chamber inside the casing 27, andthence is displaced through the outlet oritlce connection 20, the nipple36, and is expelled through the nozzle 37, as shown by the arrowsin-Fig. 2 oi the drawings.

By this construction, the nozzle 87 may be directed in any direction inthe plane of its longitudinal axis by swivelling the unit 15 at thenipple connection between the same and the support 30, and thismanipulating or directing of the nozzle may be readily aecomplished simply by grasping the conveniently located handle 22.

At times it may be desirable to limit the amount ot' air displaced bythe fan 26, and: for this purpose a valve 3% vis provided,v pivoted at4() onzthe .support 30. There-may also be provided on the valve-39, adepending tonguev 11 lo be `:grasped between the finge-rs for movinglthe valve to any position..

'l`he valve 39 is shown in dot dash lines at 39 in Fig. il, in a.partially closed position for limiting the quantity ot air which may bedrawnl through the opening 32 tothe fanl chamber inside the casing27.

Ac slightly modified form of support is shown in Figs. and 6", whichisthe same as the construction shown'iny Figs. 2, 8 andfl exceptingr,-that thereis a sub-base 42 spaced from the support 30 as by the' pins43', for permitting air to enter between the sub-base 42 and thesup'port80. The air then travels Figs. 7 and 84 sho a: still furthermodifiedfornil ot swivel support for an air displace'- nient unit in.which the inlet orifice extension 17 o the unit may be connected bytheclamping sere-w 18, with the nipple 28, which may be inserted into` andswivelled' in the upper cylindric portionl 50, of the tubular postindiratedi generally at 51.

The lower portion of the tubular post 5]., niaqyy be flared as at 52.and may he connected by screws through its peripheral flange 54. to thesupport 55, provided with legs 56 tor contact with the table A or otherfiat surface.

The flared portion 52, of the tubular posi. 5l, may be provided with anumber of openw ings 57 for the admission ot air to the lower end of thetubular postJ as indicated by the arro in Figs. 7 and 8*. The air thentravels upward throughy the nipple 28,. and air inlet orifice extension17 to the fan chamber in the casing 27.

The construction shown in Figs. 7 and 8 does not contain an opening inthe support for all of the air enters the interior ot the tubular poetthrough the openings 57.

Tn the construction shown in Figs. 9 and 10, the nipple 60, connectedwith the air inlet orifice extension 1T, by the clamping screw 18, maybe provided at its lower portions with openings 6l, which may registerwith openings G2. in the lower portion of the tubular post (SI-3.attached to the support 64, as by screws 65, extending through theperipheral flange 66 thereof.

When the nipple is inserted in the tubular post 63, the openings 61 and62 may register for the admission of air through the same, then the airtravels upward through the nipple 60, and air inlet orice extension 17,to the interior of the fan casin 27.

When it is desired to limit t e quantity of air passing to the fan, thenipple 60 may be swivelled or rot-ated within the tubular post G3,thereby causing a misalignment of the openings 6l and 62. The support 64is spaced from the table A or other fiat surface as bylegs 67.

A still further modified form of swivel support for the air displacementunit 15 is i shown in Figs. 11 and 12. which may include a tubular post70, from which extends tripod legs 71, contacting with a table A orother fiat surface by knobs 72. The nipple 2S connected with the airinlet orifice extension 17. by the clamping screw 18, may be swivelledwithin the tubular post 70, and air is admitted at the lower end thereofas shown by the arrows in Fig. 11.

By any of the foregoing means, a simple and effective support isprovided, in which the air displacement unit of a vacuum cleaner may beswivelled, and tl'irough which air may he admitted to the inlet orificeofthe air .iisplaceinent unit. Thus the air displacenient. unit may beeffectively utilized as a hair dryer, the nozzle of which may be turnedin an;y direction in the plane of its longitudinal axis.
